​It's a common refrain that has lost all meaning in the world of sports, but in the context of this weekend's events, this cliche rings nightmarish. Following the ​Jacksonville police's admission that ​24-year-old David Katz is their suspect behind Sunday's shooting at a Madden 19 tournament, every clip of the young man has become chilling, including this one of an announcer claiming he wasn't at the event to make friends.

​​The additional context will make you shiver.

Katz, 24, of Baltimore returned to the scene and opened fire on his fellow contestants, reportedly killing three (including himself) and wounding nine.

​​More updates to come from the scene of this horrific tragedy, and as the tale unfolds, we'll likely learn far more than we could ever want to about this now-notorious individual.
